There's a question a lot of us carry around without ever saying out loud: is this actually happening in my body, or am I just imagining it?
You feel it in the tired weeks that don't match how much you slept. In the cycle that felt "off" but nothing you tracked explained why. In being told stress is probably a factor — without ever being able to see it for yourself.
That's the gap we built Cortisol Pattern™ Wands to close.
Why this is exciting for you
Right now, stress tracking falls into a few camps. Wearables estimate stress through indirect signals like heart rate and HRV. Lab tests measure cortisol at a single point in time, and require a visit or a mailed sample. At-home saliva tests capture a moment-in-time snapshot.
None of them are built to show you your own pattern, over time, at home.
Mira Cortisol Pattern™ Wands measure urinary free cortisol — a biological signal related to stress patterns — through repeated at-home testing. Instead of one data point, you get a pattern you can actually follow, built around your own baseline rather than a population average.
We designed this with you in mind
We heard the same thing over and over from women tracking their cycles and hormones: stress feels constant, but it's invisible. In fact, 84% of Mira users say they're highly interested in understanding how stress affects their hormones, cycle, or overall health¹ — yet most aren't tracking it today. Most people experience it daily or close to it, yet very few actually track it — and the tools that exist tend to show what you're feeling, not the pattern behind it.
For women already tracking with Mira, the gap was even more specific: you want to see stress alongside the hormone data you already have, not as one more disconnected app. Cortisol Pattern™ Wands are designed to slot into the tracking you're already doing — no second Monitor, no new sample type, no separate app to learn.
How this works for you
Mira Cortisol Pattern™ Wands are a wellness tool for tracking stress-related patterns over time, viewed alongside your cycle, hormones, and daily routine.
They are not a diagnostic or medical device, and they're not a lab-accuracy tool. And importantly, this isn't a "stress equals cortisol" product — cortisol can shift for all kinds of reasons that have nothing to do with stress, from exercise to illness. So we talk in terms of stress patterns and load, not a single number that tells you whether you're "high" or "low."
How it works
Testing takes minutes with the Mira Monitor you already know: dip a Cortisol Pattern™ Wand into your sample, insert it into the Monitor, and see your result in the app.
You can test once a day, and some people test twice, depending on how much insight you want — you can also test alongside your other Mira Wands, following your usual schedule. A first-morning test gives you a consistent daily reference point. Adding an evening test helps you see your daily stress rhythm — typically higher in the morning and lower as the evening goes on — and notice whether your body seems to be winding down as you get closer to sleep.
With about a week of consistent testing, Mira builds your personal baseline — what's typical for you — so that later results are meaningful against your own starting point, not someone else's average. From there, you can start to notice shifts: a stretch of days that trends differently, a pattern that seems to line up with a busy week, a rhythm that starts to shift as your routine changes.
If you're feeling this way, we designed this for you
Designed to support your well-being through every stage of your journey — from TTC and cycle tracking to hormonal changes, perimenopause, and beyond.
Sleeping but never rested? See whether stress patterns remain elevated overnight and over time — beyond just a sleepless night.
Stressed but can't point to why? Track your stress patterns to see whether they stay elevated even on quieter days — and how they show up alongside the rest of your routine.

Stress can be part of every stage of your journey. Mira helps you track your stress patterns over time and view them alongside your cycle, daily logs, and personal routine. Understand your baseline, spot what's shifting, and build habits that keep up with your body. Make informed lifestyle changes and feel more confident in your wellness routine.
And if you're new to Mira altogether and simply curious about your own stress patterns — whether you're wired but tired, running on empty by 2pm, or just want to understand your body better before things feel like too much — Cortisol Pattern™ Wands are a place to start noticing, before anything builds up.
